Limestone Powder: Limestone powder is a general term for the powder of stones, which come in various types depending on their mineral composition. It is not always calcium carbonate. Calcium carbonate is a type of limestone powder, but there are also talcum powder used for making putty and quartz powder for glassmaking. Many other rocks with different mineral compositions can be ground into powder for various industrial processes and applications.
Limestone powder has a wide range of applications, and products made from it are ubiquitous in our daily lives, such as plastics, calcium tablets, clothing, and more.
Ultra-fine Stone Powder: Widely used in rubber, papermaking, coatings, aluminum profiles, ceramics, cement, glass, metallurgy, refractory materials, food, daily chemical products, artistic construction, and high-end decoration and renovation applications. Particularly, when used in coatings and papermaking, it can directly reduce the usage of titanium dioxide by 3-10%, thereby significantly reducing product costs. The high-quality marble (dolomite) ultra-fine stone powder's application in the paper industry is for pulp filling (coated paper, copperplate paper, etc.), serving to enhance opacity and improve the flexibility of the paper.
